Studies on Influence of Weather Parameter on the Activity of Soapnut Semilooper Monitored through Light Trap Catches at Devarakonda of Nalgonda District, Telangana

To understand the influence of weather parameters, correlation study made on the number of adults trapped through the light trap and the larval population on soap nut. Total rainfall, minimum temperature and relative humidity (morning and evening) showed significant positive correlation with light trap catches and larval population; where as maximum temperature had significant negative influence on both the parameters. Step down co-relation coefficient suggested that total rainfall, minimum temperature, morning and evening relative humidity are the most important weather parameters which determine the population build-up of Tinolius eburneigutta.
